I'm not quite sure how to interpret this question, so I'm going to provide you with two different answers:

The minimum value of friction is equal to the net applied force parallel to the surface. As you keep adding more force, you will reach a peak where friction is equal to the maximum static friction. If you overcome that, the object starts moving and you get kinetic friction.

The minimum value of friction is equal to 0, which happens when the object is on a perfectly smooth surface like ice.
